Queclink GV300 is a compact system designed for hid set up in the car. There are both inside and external GPS antennas: in other words, exterior antenna is optionally available. The device is embedded with rechargeable backup battery. Three LED indicators assist through the installation and diagnostic. Queclink GV300 isn't waterproof. Thanks to GNSS chip from ublox and functional firmware Queclink GV300 helps: multi-system navigation (GPS and GLONASS), Assisted GPS (A-GPS) technology and Cell ID primarily based location. The general sensitivity is good enough (if essential you may connect an external GPS antenna). Together with adjustable tracking modes all of those guarantee reliable and correct GPS monitoring. There are number of inputs in GV300, ItagPro together with analog ones, which permit to attach a number of automobile sensors of various varieties. To manage exterior tools a few outputs is used. One serial interface (kind RS232) lets connect, on user’s selection, digital gas stage sensor, iTagPro device digital camera, PND (Garmin protocol is supported) or external CAN reader. As a GPS tracker producer Queclink is well known for iTagPro its practical gadgets with complete firmware, and GV300 shouldn't be the exception. The firmware permits to configure numerous options (including remote management over GPRS), detect a wide range of occasions, read information from CAN bus and digital fuel level sensors, use Garmin-compatible PND, monitor driving behaviour. The firmware of Queclink GV300 might be updated OTA (Over-the-Air). There is only one RS232 serial interface, which is usually a limitation if you would like to connect multiple digital units, i.e. two gasoline sensors or fuel sensor and digital camera. For these cases RS485 interface can be higher, however there is no such an interface.
The outcomes obtained in laboratory checks, using scintillator bars read by silicon photomultipliers are reported. The present approach is the first step for designing a precision monitoring system to be placed inside a free magnetized volume for the cost identification of low power crossing particles. The devised system is demonstrated in a position to supply a spatial resolution higher than 2 mm. Scintillators, iTagPro geofencing Photon Solid State detector, particle monitoring devices. Among the many planned actions was the development of a mild spectrometer seated in a 20-30 m3 magnetized air volume, ItagPro the Air Core Magnet (ACM). The entire design ought to be optimised for ItagPro the dedication of the momentum and cost of muons in the 0.5 - 5 GeV/c range (the mis-identification is required to be lower than 3% at 0.5 GeV/c). 1.5 mm is required inside the magnetized air volume. In this paper we report the results obtained with a small array of triangular scintillator bars coupled to silicon photomultiplier (SiPM) with wavelength shifter (WLS) fibers.
This bar profile is right here demonstrated ready to supply the necessary spatial decision in reconstructing the position of the crossing particle by profiting of the charge-sharing between adjacent bars readout in analog mode. SiPMs are wonderful candidates in changing commonplace photomultipliers in many experimental situations. Tests have been performed with laser beam pulses and ItagPro radioactive source with a view to characterize the scintillator bar response and ItagPro SiPM behaviour. Here we briefly present the noticed behaviour of the SiPM used in our checks relating to the primary sources of noise and the impact of temperature on its response and linearity. Several models and packaging have been thought of. The main supply of noise which limits the SiPM’s single photon resolution is the "dark current" charge. It is originated by cost carriers thermally created in the sensitive quantity and present in the conduction band and due to this fact it will depend on the temperature. The dependence of the darkish present single pixel fee as a operate of the temperature has been investigated utilizing Peltier cells so as to change and keep the temperature controlled.
Dark present rate depends additionally on the Vwk as shown in Fig. 3. With a view to have low rates of darkish current the value of Vbias has been mounted at 1.5 V giving a working voltage Vwk of 29 V. It is clear that, ItagPro if obligatory, it can be convenient to use a bias voltage regulator which robotically compensates for ItagPro temperature variations. Not always the pixels of the SiPM work independently from each other. Photoelectrons (p.e.) can migrate from the hit pixel to another in a roundabout way fired by a photon. Optical cross-talk between pixels results in a non-Poissonian behaviour of the distribution of fired pixels. An estimate of the optical cross talk chance could be obtained by the ratio double-to-single pulse charge as a operate of the temperature. The chance depends weakly on the temperature and the measured stage of cross-speak (15-16%) is suitable with the one reported in the datasheet. SiPM response once its basic parameters and iTagPro locator cells configuration are given.
